The constancy of crime hypothesis: Historical evidence from Plymouth Colony

In extending Durkheimian thought on the relationship between deviance and social order, Erikson (1966) advanced the constancy of crime hypothesis, maintaining that the volume of deviant behavior remains stable over time. Erikson's data for Essex County do show remarkable stability for the years 1651–1680 in the reported offender rate. However, Essex County represents a very limited test of the hypothesis. We present comparative historical data for the entirety of Plymouth Colony, 1633–1679, finding that change—not constancy—best characterizes the evidence. The lack of unequivocal support for the hypothesis suggests a need for its rethinking. Several such possibilities are briefly discussed.We wish to thank our colleagues David L. Smith, Charles J. Dudley, Michael Hughes, Richard Schuster, Alan C. Acock (Sociology), A. Roger Ekirch (Department of History) and the anonymous reviewers ofQualitative Sociology for their helpful suggestions on a prior version of this paper.

School performance, academic aspirations, and drug use among children and adolescents

The relationship between drug use, school performance, and academic aspirations among 446 Anglo and Hispanic youths, age nine to seventeen, is explored. Two groups of subjects--current substance users and non-users--were interviewed. Subjects in each comparison group were similar in age, ethnicity, and gender. Overall results, consistent with prior research, indicate a significant relationship between current school performance, future educational aspirations, and drug use. No difference was noted between substance use groups on indicators of general interest in school work or probability of dropping out of school. Important differences in response patterns occurring with age, ethnicity, and gender were found.     

BASIC FAMILY THERAPY SKILLS,II: STRUCTURAL FAMILY THERAPY1

The Basic Family Therapy Skills Project has yielded empirically derived skills important for beginning family therapists. This article reports the results of ratings from the 103-member panel of experts who practice and teach Structural Family Therapy. A total of 100 competencies of Structural Family Therapy were rated in terms of importance on a 5-point Likert scale by the panel. Panelists were also given alternative responses such as “appropriate as a generic skill,”“inappropriate for beginning therapists,” and “don't understand what this means.” Rationale for the approach and results are discussed in terms of the importance of empirically based competencies for the practice of Structural Family Therapy.     

Regularities and irregularities in a random 0,1 sequence

A few properties of the random 0,1 sequences are studied. These properties can be utilized to test the randomness of a 0,1 sequence produced by a computer (random generator). This test seems to be appropriate for discovering the periodicity (or the length of the period) of a pseudorandom sequence. A possible application of the presented results in regression analysis is also discussed.     

Quality Provision with Heterogeneous Consumer Reservation Utilities

This study examines a firm's quality and price decisions when consumers differ not only in their willingness‐to‐pay for quality but also in their reservation utility for the basic product. We find that while the firm offers lower‐quality products when consumers' valuations for quality deteriorate, the optimal quality may increase with a negative shift in consumers' reservation utilities. We also investigate the optimal price and quality of the products within a vertically differentiated product line when the number of products is exogenously given. The existing literature shows that when consumers differ only in their willingness‐to‐pay for quality, the firm sets the efficient quality for consumers with the highest valuation for quality, whereas the concern for cannibalization pushes down the quality of inferior products. We find that when consumers are heterogeneous in both their reservation utility and valuation for quality, the concern for cannibalization may distort the quality upwards, even for consumers with the highest willingness‐to‐pay for quality. In addition, a low‐quality product may enjoy a higher profit margin than a high‐quality product within the product line.     

Managing Demand Uncertainty through Core Acquisition in Remanufacturing

We discuss the optimal raw material acquisition strategy for a third party remanufacturer (3PR). We specifically investigate whether a 3PR should acquire used products or cores in bulk with uncertain quality levels, or in sorted grades with known quality levels; and whether to acquire and remanufacture cores before the demand is realized (planned acquisition), or after the demand is realized (reactive acquisition), or on both occasions (sequential acquisition). When only sorted cores are acquired, we find that, (i) it is optimal to acquire cores in multiple grades to balance acquisition and remanufacturing costs; (ii) if reactive acquisition is possible, it reduces the assortment size (number of grades in which cores are acquired) and the total inventory acquired in the planned acquisition; and (iii) the optimal portfolio of grades to acquire and the optimal acquisition and remanufacturing quantities of these grades can be determined analytically. When bulk cores are acquired in addition to sorted cores, the property of reduction in assortment size of the planned acquisition is preserved. We also show that the 3PR should acquire only a fraction of the demand in planned acquisition, and leave the rest for reactive acquisition. This fraction changes during the lifecycle of a remanufactured product. Using a combination of empirical and realistic data from a smartphone remanufacturer we show that sequential acquisition increases expected profit by up to 8% and 27% over only planned and only reactive acquisitions respectively, and reduces the inventory acquired by up to 21% over only planned acquisition.     

Individual Differences in Women's Salivary Testosterone and Estradiol Following Sexual Activity in a Nonlaboratory Setting

Objectives: The current study evaluated women's salivary testosterone and estradiol levels before and after exposure to sexual stimuli in a U.S. sex club. Methods: Behavioral data and salivary samples were collected from 19 women during semistructured interviews. Results: Findings demonstrate substantial individual differences in the magnitude and direction of women's hormonal changes following sexual activity. Conclusions: In an age of individualized medicine, these findings highlight the need to better understand factors shaping variation in physiological responses to sexual activity. Findings contribute to a relatively small and contradictory literature on women's hormonal responses to sexual stimuli.     

Squaring Up: Experiences of Transition from Off‐Street Sex Work to Square Work and Duality—Concurrent Involvement in Both—in Vancouver,BC

Many studies of exit from sex work are inspired by role theory, where people experience a lack of attachment to a role; are faced with individual, interactional, and structural challenges; contemplate transition and exit a role; and then struggle to establish postrole identities and new lives. This framework has been used to explicate the factors and experiences of those who leave or attempt to leave the sex industry; however, it is limited because studies present sex work as a harmful and dangerous profession that people are trapped in, escaping, or have survived. In this paper, I discuss Vancouver's history of violence against sex workers and I review research on sex work exiting and bring forward recommendations for the design of exit program based on the experiences of 22 active and former off‐street sex workers from Vancouver, British Columbia. I describe study participants who include Sex‐Work‐No‐More participants who would not return to the industry, Sex‐Work‐Maybe participants who consider reinvolvement, and Dual‐Life participants who are employed in sex work and conventional work simultaneously. These participants uniquely challenge narrow, binary understandings of involvement and transition because they discuss their use of deception to obtain resources needed to make change; the support that clients have provided; their strategic engagement in sex work as a means to exit; their considerations of reentry; and for some, their dual employment. In light of new legislation that criminalizes activities related to sex work—the Protection of Communities and Exploited Persons Act—and the Federal government announcement of $20 million dollars for the creation of exit services nationwide, hearing from sex workers is essential to advancing agendas in this area. De nombreuses études de la sortie du travail du sexe sont inspirées par la théorie des rôles, où les gens éprouvent un manque d'attachement à un rôle; sont confrontés à des défis particuliers, interactionnelles et structurelles; contempler transition et quitter un rôle; et ensuite du mal à établir des identités post‐rôle et les nouvelles vies. Ce cadre a été utilisé pour expliquer les facteurs et les expériences de ceux qui quittent ou tentent de quitter l'industrie du sexe; Cependant, elle est limitée parce que le travail présente des études de sexe comme une profession nocive et dangereux que les gens sont piégés dedans, échapper ou ont survécu. Dans cet article, je discute de l'histoire de la violence contre les travailleurs du sexe de Vancouver et je passe en revue la recherche sur le travail du sexe sortant et de formuler des recommandations pour la conception d'un programme de sortie fondée dans les expériences de 22 travailleurs actifs et les anciens hors rue sexe de Vancouver CB Je décris les participants à l'étude qui incluent le travail du sexe‐No‐More participants qui ne reviendrait pas à l'industrie; Sex‐travail, peut‐être les participants qui considèrent réengagement; et les participants Dual‐vie qui sont employés dans le travail du sexe et le travail classique simultanément. Ces participants contestent unique, ententes binaires étroites de la participation et de la transition parce qu'ils discutent de leur recours à la tromperie pour obtenir les ressources nécessaires pour apporter des changements; le soutien que les clients ont fourni; leur engagement stratégique dans le travail du sexe comme un moyen de sortir; leurs considérations de rentrée; et pour certains, leur double emploi. À la lumière de la nouvelle législation qui criminalise les activités liées au sexe de travail ‐ Loi sur la protection des collectivités et des personnes victimes d'exploitation ‐ et l'annonce du gouvernement fédéral de 20 millions de dollars pour la création de services de sortie à l'échelle nationale, l'audition de travailleurs du sexe est essentielle pour programmes faisant la promotion dans ce domaine.
